i had open a MCX commodity account in a broking company. when i open account they told me that my brokerage is 0.002% and first 3 days the brokerage is same as they said but from 4th day they charged 0.03% without my knowledge. they committed 0.01% when i open the account. Now when i calculate they charged me Approx. Rs. 9500 extra brokerage. Plz tell me what i do? how to recover my money from them?
